Problems solved by technology

[0004] However, as the production site and planting scale of Pleurotus ostreatus become larger and larger, due to the backward technology, the water retention effect of the culture medium is poor in the existing cultivation process of Pleurotus ostreatus. Therefore, for the above-mentioned problems, it is urgent to study a new type of Pleurotus ostreatus cultivation method

Abstract

The invention discloses a preparation method of a water-retention culture medium for oyster mushrooms. The method comprises the following steps of calcining corn straw, conducting cooling and pulverizing, adding xanthan gum for grinding, adding polyethylene glycol and water for stirring, adjusting the pH value of a system to be 6-6.4, adding glutaraldehyde under a stirring state, adjusting the temperature for stirring, and conducting filtering, washing and drying to obtain a mixed material; uniformly mixing fermented peony seed husks, peanut shell powder, bamboo charcoal powder, coal gangue, bentonite and lime, conducting pulverizing and sieving, adding water, and accumulating the mixture for fermenting to obtain a fermented material; adding the mixed material and diatomite into the fermented material, stirring the mixture uniformly, adjusting the pH of the system to be 8.1-8.4, and conducting sterilization to obtain the water-retention culture medium for the oyster mushrooms. The culture medium obtained by the method is moderate in nutrient release rate, good in water and fertilizer retention effect, low in cost and high in economic benefit.

Description

technical field [0001] The invention relates to the technical field of mushroom planting, in particular to a preparation method of a water-retaining medium for oyster mushrooms. Background technique [0002] Pleurotus ostreatus, also known as Pleurotus, Pleurotus officinale, Oyster Mushroom, Black Peony Mushroom, is also known as Xiuzhen Mushroom in Taiwan. The life history of Pleurotus ostreatus is that basidiospores are produced when the fruiting body matures, and the basidiospores are ejected from the gills of the mature fruiting body, and when they encounter a suitable environment, they grow germ tubes, which are multinucleated at the initial stage and soon form a septum. Sequential and dense, without the phenomenon of "yellow shoots", old bacterial skins tend to appear after a few days of growth, and the bacterial skins are tight and hard. Chinese medicine believes that mushrooms are warm in nature and sweet in taste. It has the effects of chasing wind and dispelling ...
